We've been waiting for April showers, and here they come.

In fact, heavy rain is likely across all of Michigan this week.

The heaviest rain will fall in the northern half of the Lower Peninsula and all of the Upper Peninsula. Rainfall totals in this region could range between one and a half and two and a half inches by Friday.

The southern half of the Lower Peninsula will get in on the rain too, with rainfall of three quarters of an inch to a little over an inch by Friday.
